Regex Match And Not Match

Tutorial ini digunakan untuk mengeliminasi data dengan baris baru, ada contoh kasus dimana saya harus mencari data dengan pola xx42bb ... regex yang saya pakai adalah 

/(?:[\r\n]+|^)xx42.*/

Kemudian jika saya ingin mencari data selain xx42bb ... maka regex yang saya pakai adalah 

/(?:[\r\n]+|^)((?!xx42).*)/

Anda dapat praktek langsung menggunakan browser Chrome dan memakai extension https://chrome.google.com/webstore/detail/chrome-regex-search/bpelaihoicobbkgmhcbikncnpacdbknn?utm_source=chrome-ntp-icon
